<!--
	This file contains the DTD for the XML flat file of iSNS
	Persistent Data Store. It defines the XML Nodes and format
	of iSNS Objects and iSNS Attributes of the Objects.

	There are six iSNS Objects: Network Entity, Portal, iSCSI
	Storage Node, Portal Group, Discovery Domain Set and
	Discovery Domain. Each object will be defined as a XML Node.

	All of UID attribute and Key attributes of each iSNS Object
	will be defined as attributes of a XML Node. Other iSNS
	Attributes of each iSNS Object will be defined as child
	elements of the XML Node.
